Cislunar space has become the focal point of considerable interest and strategic planning because of the many proposed missions to send crews to the moon in the next decade. These include NASA’s Artemis program, China and Russia’s International Lunar Research Station (ILRS), the European Space Agency’s Argonaut program and others. The long-term goals of these […]

Black holes are often portrayed as cosmic gluttons that swallow everything that comes too close. But new observations of a dramatic black hole outburst—led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura—suggest the reality is much messier.

Every year, thousands of satellites are launched into orbit around our planet. The result is an increasingly congested “space” above Earth populated by equipment that provides services to the surface. At the same time, these satellites affect ground-based astronomy and create the potential for damage when they eventually fall through Earth’s atmosphere to the surface. […]

In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet’s main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA’s James Webb Space Telescope (JWST), a team of Caltech researchers has observed […]

Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor.

A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery demonstrates that these explosive winds affect the vast expanse of space beyond the galaxies they inhabit.

Astronomers have built the first three-dimensional map of gas temperature in the space surrounding our solar system, revealing a far messier and more dynamic picture than current models predict. The study was submitted to the arXiv preprint server on July 16.
